Docker for Gogs

Visit Docker Hub or Quay see all available tags.

Usage

To keep your data out of Docker container, we do a volume(/var/gogs -> /data) here, and you can change it based on your situation.

# Pull image from Docker Hub.
$ docker pull gogs/gogs

# Create local directory for volume.
$ mkdir -p /var/gogs

# Use `docker run` for the first time.
$ docker run --name=gogs -p 10022:22 -p 10080:3000 -v /var/gogs:/data gogs/gogs

# Use `docker start` if you have stopped it.
$ docker start gogs

Note: It is important to map the Gogs ssh service from the container to the host and set the appropriate SSH Port and URI settings when setting up Gogs for the first time. To access and clone Gogs Git repositories with the above configuration you would use: git clone ssh://git@hostname:10022/username/myrepo.git for example.

Files will be store in local path /var/gogs in my case.

Directory /var/gogs keeps Git repositories and Gogs data:

/var/gogs
|-- git
|   |-- gogs-repositories
|-- ssh
|   |-- # ssh public/private keys for Gogs
|-- gogs
    |-- conf
    |-- data
    |-- log

Volume with data container

If you're more comfortable with mounting data to a data container, the commands you execute at the first time will look like as follows:

# Create data container
docker run --name=gogs-data --entrypoint /bin/true gogs/gogs
# Use `docker run` for the first time.
docker run --name=gogs --volumes-from gogs-data -p 10022:22 -p 10080:3000 gogs/gogs

Using Docker 1.9 Volume command

# Create docker volume.
$ docker volume create --name gogs-data

# Use `docker run` for the first time.
$ docker run --name=gogs -p 10022:22 -p 10080:3000 -v gogs-data:/data gogs/gogs

Settings

Application

Most of settings are obvious and easy to understand, but there are some settings can be confusing by running Gogs inside Docker:

Repository Root Path: keep it as default value /home/git/gogs-repositories because start.sh already made a symbolic link for you.
Run User: keep it as default value git because start.sh already setup a user with name git.
Domain: fill in with Docker container IP(e.g. 192.168.99.100). But if you want to access your Gogs instance from a different physical machine, please fill in with the hostname or IP address of the Docker host machine.
SSH Port: Use the exposed port from Docker container. For example, your SSH server listens on 22 inside Docker, but you expose it by 10022:22, then use 10022 for this value. Builtin SSH server is not recommended inside Docker Container
HTTP Port: Use port you want Gogs to listen on inside Docker container. For example, your Gogs listens on 3000 inside Docker, and you expose it by 10080:3000, but you still use 3000 for this value.
Application URL: Use combination of Domain and exposed HTTP Port values(e.g. http://192.168.99.100:10080/).

Full documentation of application settings can be found here.

Crond

Please set environment variable RUN_CROND to be true or 1 in order to start crond inside the container.

Upgrade

❗❗❗Make sure you have volumed data to somewhere outside Docker container❗❗❗

Steps to upgrade Gogs with Docker:

docker pull gogs/gogs
docker stop gogs
docker rm gogs
Finally, create container as the first time and don't forget to do same volume and port mapping.

Known Issues

The docker container can not currently be build on Raspberry 1 (armv6l) as our base image alpine does not have a go package available for this platform.
